The compound is made as follows: For ten parts of compound take per weight two parts of soda, one part of alum; three-fourths part of horax, one-fourth part of potash. These ingredients are powdered and mixed, and then six parts of weter-glassare added thereto in a.

The composition will soon turn into a solid stone-like substance. This substance may be readily shipped and stored away ready for use. When it is to be used it is mixed with water and will dissolve therein in a.- very short time. The water may he of any temperature. The

proportion should beabout one and a. half pound to one gallon of water.
